520c: Help Needed

Recommended Posts

Better to flip back to original position since Vmain is 1.5A. With only 1A you may run out of power when using floppy drive with backlight at max intensity for example... and it will stress your power supply uselessly ;)

Alright. Luckily I used duct tape to seal my bodgework so while it looks like a growth it does work (for the time being) and I can just take the tape off to reverse it.

 

Do you suggest I just dremel the PSU brick open, or should I still try getting it apart with a flathead screwdriver (despite already having chipped the plastic)?

For what it's worth, I bought a IBM 16V 4.5A PSU on eBay, and connected the red & orange wires from the Powerbook cable to the positive, and everything else to negative.

My Powerbook 520 works just fine.

Although since the batteries are dead, I can't say if the charge circuit is fully working.....

 

Here's the one I bought:
